SURE-LEGAL INSTEQULIIENT.

Application filed June 5, 1935:.

v. of this invention is to supply in. Mn .1. to facilitate the labor ofphysicians when inc ing examinations to" determine the coiulitions ofsubjects or patients, the instrument being specially designed forobstetrical work and to overcome nearly 21s practicable the ni'inoyenceand discomfort generally experienced ehlte both by the subject and thephysician or veterinaria-u'i during the examination.

The invention consists of the novel features, details of constructionand combinations of parts which hereinafter will be more particularlyset forth, illustrated in the accompanying drawings end pointed/out inthe appended claims.

Referring to the drawings forming a part of the specifications: Figure 1is a side view of an instrument embodying the invention parts beingbroken away to show more cl ly the r lative arrangement of the co igelements. Fig. 2- is strensvcrse n on the line 2-2 of Fig. 1 looking in.ction ol? the arrow. Fig. is a cross on the line of Fig. 1 looking toright as indicated by the arrow. 1 r spondingend like parts are referredthe following description and indiin all the views of the drawings by hesome reference characters.

The instrumentcoruprises essentially two perts it and E, the part Abeing designated s cilzitor because ft its function and the part Breferredto hereinafter as the body since it supports the adjunctivepart,

-1e dietor A is of less diameter and size the body end is arranged at anobangle to said body for convenience of The dilator comprisesessentially two parts light tube 1 and a reflecting tube 2, the latterbeing of larger diameter end pro vided st outer end with a lens 3. tubes1 and are placed side by side enveloped by means of e sheath or l, whichcloses the spaces formed bethe two tubes and prevents any foultheinstrument and enables the some dily and Specification of Letterslatent.

two tubes 1 and 2 are of substantially equal length so that their outerends come about flush. A lens 5 1s provlded at the outer end oi thelight tube 1. A lens 6 is fitted to the outer end of: the sheath orcasing l. and is jointed thereto so as to present a smooth joint which.will prevent retention of any matter and avoid injury to tissues ormembrenes.

The body 8 comprises a telescope 7, a. con ductor tube 8 and a batterycase 9. The parts 7, 8 and 9 are protected by means of esheeth or casing10.

An illuminetor 11 is located at the juncture of the light tube 1 and theconductor tube 2 so as to shed rays of light through the light tube uponthe port to be cxzuuincd. A reflector 12 located in the rear of theilluminutor ll gathers-end throws the rays of light through the tube 1..The illuminutor 11 is preferably of the electric type and consists of anincandescent lamp receiving current from the battery located in the case9 by means of electric conductors 18.

A circuitclosure 14 is located near the inner end of the battery caseand comprises a push button which may be pressed inward when it desiredto complete the circuit to below the object lens 16 in line with therefleeting tube 2 so as to receive the object rays and reflect the someto the part 17 and the letter in turn reflecting the same to the lens 16and telescope to the eye-piece thereby admitting of proper inspection ofthe part to be examined as will be readily understood.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the coustrcclion and of themethod of operation will be readily apparent to those skilled in the artto which the invention a 'n crtains, and while I have described theprinciple of operation of the invention, toget ier with the device whichI now consider to be the best elnbcdiment thereof, l desire to have itunderstood that the device shown is merely illustrative and that suchchangesmay be made When dean obtuse angle thereto, said dilatorconsisting of a light tube and a reflecting tube and said bodycomprising a telescope and a conductor tube, an illuminator located atthe ,juncture of the light and conductor tubes, and complementalreflectors located at the "juncture of the reflecting tube and telescopeso as to reflect the object rays from the reflecting tube through thetelescope.

2. In an instrument of the character described, comprising a bodyportion and a dilator arranged at an obtuse angle thereto, said dilatorconsisting of a juxtaposed light and reflecting tubes having lenses attheir outer ends, a sheath inclosing the two tubes, and a lens at theouter end of the sheath and protecting the outer ends of the said tubesand the lenses thereof. g

3. In. an instrument of the character-described, the combination of a'dilator comprising juxtaposed light and reflecting tubes, an illuminatorfor shedding rays of light goes through said light tube, com'plemental're-- 3 tube. dilator at one end of the body arranged at 4:. The hereindescribed surgical instrument comprising a dilator and a body having arelatively obtuse angle arrangement, the dilator consisting of light andreflecting tubes provided at their outer ends with lenses, a sheath.inclosing said tubes and. provided at its outer end with a lens, saidbody comprising a telescope, a conductor tube and a battery case, theparts being inclosed by means of a sheath, an electric illuminatorlocated at the inner end of said light tube,

'complemental reflectors at the inner end of said reflecting tube, thetelescope having its inner end arranged to receive the 0b ectrays fromsaid reflectors, and means for closing the circuit through the electricilluminator.

In testimony whereof I aflix my signature in presence-of two Witnesses.
